Mike Tyson thinks that his whole life is a joke. At least, that's what he writes in a new book called Undisputed Truth that borrows the same title he used for his one-man show about his life. In the autobiography, Tyson admits that there are some pretty crazy thoughts that creep into his mind from time to time.

"Sometimes I just fantasize about blowing somebody's brains out so I can go to prison for the rest of my life," he writes in the book. "Working on this book makes me think that my whole life has been a joke."

Tyson also makes some other pretty wild admissions in the book (would you expect anything less?!). For instance, he says that he had sex with his drug counselor while he was in prison in the early 1990s. He also retells the classic story about the time he caught Brad Pitt hanging out with Robin Givens. And he reveals that he wishes he could put his hands on Don King.

"When I think about all the horrific things that Don has done to me over the years," he writes, "I still feel like killing him."

The book, which Tyson wrote with some help from author Larry Sloman, drops on November 12. And judging by what we know about it so far, it sounds like must-read material.
